Verify that the SOA record is at the same version for all authoritative servers for a specific zone.

With the assistance of the DNS administrator, identify each name server that is authoritative for each zone.

Inspect each zone file that the server is authoritative for and identify the following:

example.com. 86400 IN SOA ns1.example.com. root.example.com. (17760704;serial)
